SIAddPointOnCurveAtStart
Adds a point at the start of a curve.
SIAddPointOnCurveAtStart( InputObj, [X], [Y], [Z], [Local], [CurveType], [PreserveTrace] ); |
| Parameter | Type | Description |
|---|---|---|
| InputObj | String | Curve to set points on. |
| X | Double | X coordinate
Default Value: 0 |
| Y | Double | Y coordinate
Default Value: 0 |
| Z | Double | Z coordinate
Default Value: 0 |
| Local | Boolean | True if points are in local coordinates, False if they are in
global coordinates.
Default Value: False |
| CurveType | Integer | Type of curve
Default Value: -1 |
| PreserveTrace | Boolean | True if the current trace of the curve should remain intact
with the addition of the new point.
Default Value: False |
